🫘 CKD Staging & Referral (KDIGO)
KDIGO heat-map risk stratification (eGFR stage × albuminuria stage), follow-up frequency and nephrology referral advice for CKD. Instant, browser-side.
CKD Staging & Referral (KDIGO)
eGFR (mL/min/1.73m²)
Urine albumin/creatinine ratio (ACR) (mg/g)
When to use
Stage CKD and decide on follow-up intensity and referral; the diagnosis requires abnormalities to persist ≥ 3 months.
How it works
eGFR stages G1–G5 × albuminuria A1 (< 30), A2 (30–300), A3 (> 300 mg/g) → low/moderate/high/very-high risk per the KDIGO grid.
Key points
- Refer to nephrology for eGFR < 30, A3 albuminuria or very-high risk.
- Also refer for rapidly falling eGFR, resistant hypertension or unexplained anaemia.
- CKD requires abnormalities to persist ≥ 3 months.
- G1–G2 with A1 needs another marker of kidney damage to diagnose CKD.
